UNITED STATES PATENT OFFICE.

GUSTAV LANGENHAGEN, OF LEIPSIO, SAXONY, GERMANY.

LEATHER-POLISH.

SPECIFICATION forming part of Letters Patent No. 406,102, dated July 2,1889.

Application filed January 26, 1887. Serial No. 225,570. (No specimens.)

To all whom, it may concern.-

Be it known that I, GUSTAV LANGENHAGEN, of Leipsic, in the Kingdom ofSaxony and German Empire, have invented a new and useful ImprovedLeather-Polish, of which the following is a specification, no patentshaving been obtained by me anywhere for this invention.

My invention relates to improved leatherpolish.

All leather-polishes in use until now show many deficiencies. Purecoal-tar oilsas vaseline, for instance-are susceptible of very littleabsorption, and thereby render the leather dry and flawy. Mixtures ofcoal-tar oils-as, for instance, mixture of heavy coal-tar oil andwax-=-show the same deficiency, While pure animal and vegetable fats areliable to get rancid, and therefore are very noxious. Heregloss of theleather, and nevertheless unknown until now, there is especially to bementioned a considerable addition of oil of turpentine. The coloringsubstances are dissolved.

The leather-polish consists of the following components: Forty per cent.of carnaubawax, one per cent. of steatite, thirty per cent. of oil ofturpentine, five per cent. of aniline, (nigrosine,) two per cent. ofCongo black, eight per cent. of almond-kernel oil, four percent. ofbeeswax, and ten per cent. of ozocerite.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-- A leather-polish consisting of forty per cent. ofcarnauba-wax, one per cent. of steatite, thirty per cent. of oil ofturpentine, five per cent. of aniline, (nigrosine,) two per cent. of Congo black, eight per cent. of almond-kernel oil, four per cent. ofbeeswax, and ten per cent. of ozocerite, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

GUSTAV LANGENHAGEN.
